Continuing Professional Development. Anaphylactic shock.

The causes of anaphylactic shock and presenting features are not clearly understood. In addition, the treatment of people suffering from anaphylactic or anaphylactoid reactions has not always been effectively provided. This article aims to rectify some of the current areas of concern, especially highlighting the recent work carried out by the Resuscitation Council (UK) on this subject (Resuscitation Council UK 1999/2001). After reading this article you should be able to: Explain the circulation of the blood and changes that occur during an anaphylactic reaction. Summarise the antigen/antibody mechanism especially in relation to allergic reactions. Describe the difference between anaphylactic and anaphylactoid reactions. Recognise the presenting signs and symptoms of anaphylaxis and shock. Describe the assessment and appropriate intervention for a patient suffering from an anaphylactic reaction. Explain what prevention/support services are available to suffers.
